Let's assume we were given 2 numbers: 15 and 30. Their sum is:
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
In this case sum of two numbers can always be written as:
1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.
Answer: 50
Step-by-step explanation:
exterior angles are supplement of interior angle therefore the 110 thing must be 70, also youre given 60 so 70+60=130
50 is missing from 180
Answer:
x = -9
Step-by-step explanation:
x = -y/4
y = -2(-y/4) + 18
y = y/2 + 18
y/2 = 18
y = 36
x = -36/4
x = -9
The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
